Gen 2: 6 items that you have to equip and then trade (one of them postgame, 2 of them split evolutions), 4 friendship evoltuions which are a drag, 1 stone for a split evolution
Gen 4: 5 move relearning evolutions, 5 items to equip and trade, 2 items to equip and level up at a specific time frame, 4 that require special zones (this shit was the worst to maintain), 6 that use stones (2 of them split evolutions with required genders)
Gen 6: use the newly introduced feature for five minutes
The problem with corss-gen evos is that many of them are esoteric as fuck or a pain in the ass because you need to obtain a rare item and then also find someone to trade with. Only because they wanted to keep the "lore" consistent.
Now they don't care about that anymore but they keep adding weird evolution methods. Specific timeframes AND games! Specific weather! Specific party members! Hold the console upside-down! Get critical hits! Get hurt a lot and then walk over a specific tile! Go to a specific location that won't be avaliable in upcoming games!
It's like they didn't learn anything from the eevee rocks.
